What are the types of screening equipment most frequently used by the Department of Defense (DoD)?

• A. Fixed and portable
• B. Portable only
• C. Fixed only
• D. Digital and analog

Answer: (A)

The idea being tested is how screening equipment is categorized by deployment and portability rather than by tech features. DoD screening setups use both fixed, in-place systems at gates and facilities to provide consistent, high-throughput security, and portable devices that can be moved to remote, temporary, or field locations to extend coverage or respond to changing needs. Fixed screening equipment is ideal for permanent access control points, while portable screening tools offer flexibility for temporary checkpoints, field operations, or events. The other options mix up this practical distinction: portable only wouldn’t secure permanent gates, fixed only wouldn’t adapt to temporary needs, and digital versus analog describes how a device processes information, not whether it is fixed or portable.
